That's because Monica Rose has been dressing the Kardashians for as long as a decade, according to The Cut.

But after 10 years, Kim, Kourtney, Khloe, Kylie, and Kendall have all reportedly cut ties with the stylist who made chokers cool again, even unfollowing her on Instagram. Reports from April also alleged that Khloe is considering suing Rose.

Here's everything we know so far:

The magazine pointed out that the last time Khloe tagged Rose in an Instagram photo — as she usually did whenever she styled her — was in March. Here's the post:

People noted that Khloe hired stylist Dani Michelle — who has also been credited with styling Kourtney — for a photo shoot in April.

The split appears to be more than just a professional one, however. As The Cut observed, the sisters stopped following Rose on Instagram altogether as of April 26, which doesn't really bode well for the stylist.

A Page Six story from April 28 cites a source who said the sudden break was due to "mysterious circumstances."

On May 1, the story escalated as Page Six reported that Khloe wants to sue Rose, adding that the stylist"recently hired a lawyer to keep some of the wilder scuttlebutt out of the headlines."

Here's another excerpt from the report:

Now we've learned Kardashian's furious and wants to sue Rose over the sudden schism — but Rose says she can prove she's done nothing but a great job for Kardashian.

Meanwhile, we're told the whole affair, which began several weeks ago, is causing heartache for everyone concerned.

The publication also quoted a source close to the family, who said: "The Kardashians/Jenners are upset because [Rose] was like family to them."

While we don't know how true that is, Rose did make appearances on "Keeping Up With the Kardashians," and she has styled all of the sisters and Kris Jenner. She also has plenty of photos with members of the family on her Instagram.

On May 18, Us Weekly reported that Kris Jenner was behind the decision. A source who claims to be close to the family is quoted saying, "Kris told her girls in April to cease contact with Monica."

The US Weekly report from May 18 also cited an "insider" source, who said that Khloe didn't plan to make the details of the split with Rose public knowledge. The insider also said that the story wouldn't be addressed on "Keeping Up With the Kardashians."

Then she threw further shade at her anonymous "friend" in a final tweet on the topic:

On June 5, TMZ cited a source close to the Kardashians who allegedly said that Khloe claims her "friend" stole tens of thousands of dollars' worth of clothes.

Here's more from the TMZ report (emphasis ours):

"Khloe hasn't yet filed a lawsuit or police report, but, sources close to the situation tell us she's already talked to her lawyers, claiming the friend charged tens of thousands of dollars in designer clothes to Khloe's credit card ... clothes that didn't end up in her closet.

We're also told Khloe believes high-end designers sent her all sorts of stuff but the friend never turned it over to her.

In all, Khloe believes a small fortune was taken.

We're told Khloe's mulling over a lawsuit but hasn't decided yet. Her friends are urging her not to sue, because it will ruin the friend's career."

TMZ wrote that it has followed up with its contact but hasn't heard back. And though Khloe's tweets may sound like her "friend" could be her former stylist, we can't confirm anything yet.

A few days earlier, on May 28, Kim — who was the first to work with Rose after a Complex photoshoot in 2007 — revealed her own reason for why she quit working with Rose years ago during a round of "Plead the Fifth" on Andy Cohen's "Watch What Happens Live."

Kim said her decision to stop working with the stylist is separate to her sisters' reason for cutting ties with her.

"I haven't worked with her in maybe four years, so my reason is not connected to this," she told Cohen. "I will say that I read that it was said that she was the reason for my makeover — my makeover when I met Kanye —and I will say that Kanye got me a new team and we kind of documented it. So I think people think that's the reason, and for me, maybe that is the reason. I needed a new vibe."

While Kim said she just wanted a new look, it was clear that she didn't want to talk about the drama. At the end of the round, which only lets you "plead the Fifth" on one question, she said, "I should have pleaded the Fifth on Monica!"

Even Gigi Hadid, who is a friend of the family, has reportedly stopped working with Rose.

As for Rose, she has continued to work with celebs including Jenna Dewan Tatum and Chrissy Teigen, who she styled for the 2017 Met Gala.

Rose has remained silent on social media, and in recently published interviews with StyleCaster and Teen Vogue she has mentioned, and even praised, Kendall Jenner.

Speaking to Teen Vogue in April, she called Kendall "awesome" and "the coolest chick."

In the past, Khloe has spoken highly of Rose.

"At my fattest, Monica would always come with racks of clothes and make me feel special," she told Harper's Bazaar in June, 2016. "She never told me, 'Oh, they don't have that in your size.' Other people actually said, 'I just can't work with you' — because I was too big. That always hurt my feelings, of course."

A year later, it seems their relationship is nowhere near as strong.

Although it remains unclear what exactly went down between the Kardashians and Rose, we'll keep updating this story as we learn more.
